About
I’m Shkelqim Sina, a senior full stack software engineer with 15+ years of experience building scalable, production-ready web applications and data-intensive user interfaces. I’ve worked across the full delivery lifecycle—turning complex requirements into system designs, implementing robust backend services and interactive frontend experiences, and ensuring quality through automated testing and reliable deployments.
I especially enjoy geospatial and visualization work: integrating PostGIS-powered backends with rich 2D/3D frontends using WebGL and mapping technologies such as ArcGIS Maps SDK and CesiumJS. I collaborate closely with founders and stakeholders, prototype quickly, and independently own architectural decisions, implementation, monitoring, debugging, and ongoing production support—particularly in fast-moving, early-stage environments.

Work experience· 8 roles
Designed and built production-ready full-stack product and geospatial applications from the ground up using Ruby on Rails, React, JavaScript/TypeScript, PostgreSQL, and REST APIs. Delivered computation-heavy, parameter-driven React interfaces with real-time updates, complex state management, and data visualization. Implemented backend services including authentication, business logic, background jobs, and asynchronous workflows for data-intensive features. Modeled relational and geospatial data in PostgreSQL/PostGIS with spatial indexing and optimized geographic queries. Built 2D/3D mapping experiences with WebGL, ArcGIS Maps SDK, CesiumJS, and interactive map layers, integrating frontend mapping with backend geospatial APIs. Owned the full delivery lifecycle: architecture, implementation, Git workflows, testing (unit/integration/API/E2E), deployment, monitoring, debugging, documentation, and production support.
Built production-ready web applications using modern backend, frontend, API, database, and cloud technologies in a fast-paced environment. Designed reusable application architecture, backend services, frontend components, and clear integration boundaries with maintainability and testability in mind. Translated complex business and technical requirements into independent delivery plans and implemented features from design through release. Supported CI/CD, production deployment, troubleshooting, technical documentation, peer review, and iterative improvements.
Developed distributed, data-rich full-stack applications using React, TypeScript/JavaScript, backend APIs, SQL, and cloud-native deployment workflows with Docker and Linux. Created interactive React interfaces with real-time state updates, dynamic configuration, charts, and operational visualizations. Designed APIs, background processing, and event-driven workflows for real-time ingestion, synchronization, and distributed communication. Built reusable components across multiple applications and owned features from design through automated testing, deployment, troubleshooting, and production support.
